This is the free/basic version - it lets you get a feel for the application and lets you find out if it works with your vehicle / obd2 adapter combination; but may contain some small bugs including not working on some nissan/chrysler/subaru ECUs. The paid version has support for more vehicles and ECU types, looks a lot nicer, and works with more cars / trucks

**PLEASE NOTE!** Any reports of hanging or freezing after quitting the app is due to a bug in the HTC Evo 4G and Galaxy Tab, this can be triggered by using the Pandora/Vlingo/Aldiko bluetooth enabled apps. Disabling Pandoras new bluetooth settings fixes the problem, but HTC/Samsung need to release a fix. Please contact their support and encourage them to fix, Thanks!

The pro version supports USB ELM adapters which are use 'Prolific' or 'FTDI' chips

* Update: A freeze/hang workaround has been found after a great amount of effort and is available in the full version in the General Preferences settings!
